Akande 2 Abstract The demand for data services and necessary bandwidth have grown rapidly because of new telecommunications services like HDTV via the Internet, video on demand, etc. An increase in demand for broadband connection from private homes, companies, etc. leads to an increase in bandwidth demand in the access domain. Issues associated with copper cables being used for transmission are quite enormous, from the impervi- ousness of the material to electromagnetic interference (if it is not correctly installed). Another issue is the attenuation of a signal over a distance. The study evaluates the performance of using GPON (point to multipoint) as one of the standards of PON technologies to provide triple-play services for users. 1. Introduction The existing infrastructure for access network which was originally developed for classical telephony services is mainly on the copper cable which has limited bandwidth and reaches. Some years ago, the telecommunication system was built mainly for voice with small data capabilities.
